Definitions

  • the invention relates to a closure cap for dual chamber vessels.
  • Tubes and other containers comprising two or more separate chambers for storing and dispensing in metered doses the contents of the chambers are known.
  • cosmetics preparations are developed to an increasing extent consisting of components with are non-compatible with one another and which are mixed only when used.
  • the tube body comprises a partition fixed along two longitudinal lines, which are symmetrical about the central axis.
  • the partition is in this case additionally fixed at least in the region of the one end section of the tube body at at least one location in such a manner that the partition in the rounded cross-section of the tube body rectilinearly subdivides the latter.
  • U.S. Pat. No. 3,729,553 discloses a dual chamber vessel for a foaming composition, the solutions stored separately in the two chambers being mixed when being withdrawn together and being foamed in the process.
  • U.S. Pat. No. 5,765,725 describes a compressible dual chamber vessel comprising a closure through which the contents of one chamber may be withdrawn separately from the contents of the other chamber. For this purpose withdrawal apertures are provided in the closure comprising separate covers.
  • closure cap according to the invention is particularly suited for preparations which are to be used separately from one another, but in close relationship in a timewise or functional sense.
  • preparations which are to be used separately from one another, but in close relationship in a timewise or functional sense.
  • shampoo and conditioner for hair care or day and night care creams.
  • the cap according to the invention consists of a connecting member for establishing a connection to the vessel and a withdrawal member with which the withdrawal apertures are associated, both members being interconnected by snap elements.
  • the closure cap according to the invention is suited in particular for tubes and even permits to be adapted to withdrawal apertures which are arranged in an asymmetrical manner in relation to the partition element.
  • the snap connection ensures simple and, consequently, cost-effective production.
  • the withdrawal member may further be so designed, should this be desired, that the contents of the different chambers are mixed during withdrawal, making a re-adjustment of the vessel and the connecting member redundant.
  • the closure cap comprises means through which the contents of one chamber may be fed separately from the contents of the other chamber to the associated withdrawal aperture.
  • a partition is provided between the withdrawal apertures of the chambers in the interior of the closure cap, subdividing the closure cap into two separate regions, a withdrawal aperture being provided in each region.
  • the partition is in this context connectable to the partition element in such a manner that mixing of the chamber contents does not take place.
  • the partition may preferably be receivable in a matching groove of the partition element at the discharge aperture of the vessel.
  • the partition may likewise comprise a groove, in which the partition element may be received in formfitting relationship.
  • the withdrawal apertures are preferably arranged in spaced apart relationship, for example arranged on opposite sides in an overall round or oval closure cap.
  • the connecting member of the closure cap is preferred to comprise sections adapted to the configuration of the discharge aperture, through which sections the contents of the chambers is fed to the separate regions within the closure cap.
  • the discharge aperture of the vessel may, for example, comprise two semicircular apertures, formed by the partition element within the vessel. Consequently, the sections of the closure cap are likewise correspondingly semicircular and introducible into the apertures in close fitting relationship. The contents of the chambers is thus fed to the respective region within the closure cap and, as a result, to the associated withdrawal aperture.
  • the sections of the closure cap are designed correspondingly in quarter circles thus ensuring that the contents of one chamber is accurately fed to one withdrawal aperture.
  • withdrawal apertures are each closable by a snap closure known per se.
  • a closure of this type for a vessel comprising a single chamber is described, for example, in DE 41 23 733.
  • the connecting member of the closure cap according to the invention is connected to the discharge aperture of the vessel in a manner known per se. It may, for example, be screwed on by way of a thread moulded onto the vessel.
  • the closure cap is snap-connectable to the vessel.
  • an annular projection may be moulded on, for example, in the region of the discharge aperture overlapped by the closure cap. In comparison to a screw connection, this snap connection proves to be particularly simple and cost-effective.
  • the vessel may comprise a shoulder against which the lower edge of the closure cap fits closely.
  • Plastics materials are particularly suitable to manufacture the closure cap according to the invention.
  • the drawing shows a schematic longitudinal section through a closure cap for a dual chamber tube according to the invention.
  • a closure cap 1 is shown, closing the discharge aperture 3 of a dual chamber tube 2 .
  • the tube 2 is subdivided into two chambers 5 and 6 by a partition foil 4 serving as a partition element.
  • the contents of the chambers 5 , 6 not shown, is fed separately to the discharge aperture 3 .
  • the material strength of the partition foil 4 is reinforced in the region of the discharge aperture 3 to such an extent that the partition element is dimensionally stable.
  • a peripheral annular projection 7 is provided, overlapped by the closure cap 1 by way of a matching projection, thus fixing the closure cap to the tube 2 .
  • the closure cap 1 is designed in two parts.
  • a connecting member 1 a is snap-connected to the tube 2 by way of the projection 7 .
  • the withdrawal apertures 8 , 8 ′ are arranged in a withdrawal member 1 b .
  • the withdrawal member 1 b is snap-connected to the connecting member 1 a .
  • the lower edge of the connecting member 1 a fits closely against a shoulder of the vessel.
  • a partition 12 is provided in the withdrawal member 1 b .
  • the partition 12 is accommodated in a groove 13 in the connecting member 1 a .
  • a further groove 14 on the connecting member 1 a co-acts with the partition foil 4 in such a manner that the contents of the chambers 5 , 6 is fed without mixing to the respective withdrawal aperture 8 , 8 ′.
  • the two-piece closure cap according to the invention permits without any problem in a vessel, the partition element of which is not arranged parallel to the partition of the closure cap, to withdraw the contents of the chambers without mixing.
  • This chamfer of the partition element of the vessel in relation to the partition may, for example, be advantageous with regard to manufacturing techniques.
  • the connecting member 1 a ensures in the process the required connection between the individual chambers of the vessel 2 and the associated withdrawal apertures 8 , 8 ′ in the withdrawal member 1 b.
  • the connecting member 1 a further comprises semicircular sections 15 , which are accommodated in the discharge aperture 3 in form-fitting relationship. Through these sections 15 the contents of the chambers 5 , 6 reaches that region of the closure cap 1 with which the respective withdrawal aperture 8 , 8 ′ is associated.
  • each withdrawal aperture 8 , 8 ′ is associated with exactly one chamber 5 , 6 of the tube 2 , so that the contents of chamber 5 may be withdrawn from the withdrawal aperture 8 and the contents of chamber 6 from the withdrawal aperture 8 ′.
  • each withdrawal aperture 8 , 8 ′ is closable for this purpose by a snap closure 9 , 9 ′.
  • the two snap closures 9 , 9 ′ are structured identically, the snap closure 9 being shown in its closed state and the snap closure 9 ′ in its open state.
  • Each of the snap closures 9 , 9 ′ is formed by a plate-like cover 10 connected to the withdrawal member 1 b by a thin film hinge and serving as an actuating element, and by a projection 11 so dimensioned and arranged that the withdrawal aperture 8 , 8 ′ is closable by the projection 11 .
  • the withdrawal apertures 8 , 8 ′ are formed by recesses in the withdrawal member 1 b , comprising on the side facing the snap closures 9 , 9 ′ a chamfer for guiding the projection 11 during closing.
  • the cover 10 projects laterally beyond the closure cap 1 in order to facilitate opening the snap closure 9 , 9 ′.
  • the wall of the closure cap 1 recedes slightly in the region of the snap closures 9 , 9 ′.
  • the closure cap according to the invention permits separate withdrawal of the contents of the two tube chambers. When opening both snap closures, simultaneous withdrawal is likewise possible.
  • the selected connections by snap means result in simple and cost-effective production.
  • Even conventional dual chamber tubes may be provided with the closure cap according to the invention without complex adaptation.
  • an analogous use of the closure caps according to the invention is also possible for vessels with more than two chambers, provided appropriate spatial conditions exist. For that purpose a third withdrawal aperture with closure would have to be provided.
  • the application of other closing principles known per se instead of the preferred snap closure, for example, slidable closures, is likewise well conceivable.
  • the two-part closure cap may also be made of different types of plastics or materials and/or materials of different colours, clearly increasing, therefore, the aesthetic design possibilities.
